1. Control the temperature. During the cucumber growth period, the temperature cannot exceed 30 degrees Celsius and cannot be lower than 25 degrees Celsius. If it exceeds, then cucumber plants will grow wildly. For indoor planting, the daytime temperature should be controlled between 25 degrees Celsius and 30 degrees Celsius. The temperature at night is kept at about 18 degrees Celsius to reduce its breathing and facilitate the accumulation of beneficial substances. If the temperature is too high during the day, it is necessary to open the shed moderately to avoid the phenomenon of plant death due to the high temperature. 2. Suppress humidity. Indoor planting, in a sealed environment, the temperature and humidity will be relatively high. However, the suitable air humidity for cucumber growth is about 85%. If the air humidity in the shed exceeds 85%, ventilation and humidity reduction should be carried out immediately. If the temperature is between 10 degrees Celsius and 15 degrees Celsius at night, the greenhouse should also be properly ventilated to prevent cucumbers from "crazy growth", to suppress the occurrence of pests and diseases, and to promote flowering and fruiting of cucumbers. 3. Scientific fertilization. Excessive application of nitrogen fertilizer and insufficient fertilizers such as phosphorus, potassium, and boron will cause the plant to grow vigorously and fail to pollinate and fertilize normally, which will cause the plant to drop flowers and fruit. If the plant absorbs more nitrogen, it will be beneficial to the development of the branches and leaves of the plant, which is not conducive to its flowering and fruiting. Therefore, it is necessary to control nitrogen fertilizer and increase fertilizers with other elements. You can also spray some foliar potassium fertilizer to promote plant pollination and fertilization. In this way, it can promote its flowering and fruiting and increase the fruiting rate. In addition, the cultivation conditions should also be improved, and high-quality films should be used as much as possible in the greenhouse. A good film has good light transmittance and can avoid water accumulation on the top of the film, thereby increasing the temperature in the shed and reducing the humidity in the shed. It is necessary to scrub the greenhouse film frequently to prevent the accumulation of dirt from causing adverse direct sunlight and affecting the plants to absorb sunlight.
